I assume you are thinking of a manual key distribution between peers?
That is an option for a small scale deployment for sure. With 1000 admin
domains where every one may want to exchange secret information with
everyone else, there would need to be 1000^2 sets of keys in place. All
peers are not allowed to be in possession of any keys but those
concerning themselves. While it is technically possible (maybe), the
deployment and maintenance hurdles of such a key blob are prohibitive.

Or did you mean something completely different that we simply
overlooked? I'd be very eager to hear about it then!

Greetings,

Stefan Winter
